Q I was wondering why your product MALE should not be used by diabetics.

A It’s the arginine, which in large enough amounts can precipitate the release of growth hormone. And growth hormone can increase the level of a factor (IGF-1) that may interfere with the efficacy of insulin in the body. On the other hand, smaller amounts of arginine may increase the ability of the pancreas to release insulin more efficiently. For those with diabetes or borderline diabetes, therefore, we recommend working with a healthcare professional when using arginine.
